Humberside Police's mounted section is being axed as the force battles to meet budget cuts.
The unit, made up of six horses based in Walkington, will be disbanded next year.
Chief Constable Tim Hollis said the decision to scrap the mounted section will save £500,000 a year.
He said: "I realise the public and many officers, serving and retired, will regret the loss of a mounted section which has been an integral part of policing across Humberside for so many years.
"Personally, I share that sadness but we are in a period when sentiment has come up against austerity and hard decisions must be made."
